OPA1679 - Low-Distortion Audio Operational Amplifiers

Download the OPA1679 datasheet PDF. This datasheet also covers the OPA1678 variant, as both devices belong to the same low-distortion audio operational amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

The OPA1678 (dual-channel) and OPA1679 (quadchannel) operational amplifiers offer higher systemlevel performance over legacy op amps commonly used in audio circuitry.

Key Features

  • 1 Low noise: 4.5 nV/√Hz at 1 kHz.
  • Low distortion: 0.0001% at 1 kHz.
  • High open-loop gain: 114 dB.
  • High common-mode rejection: 110 dB.
  • Low quiescent current:.
  • 2 mA per channel.
  • Low input bias current: 10 pA (typical).
  • Slew rate: 9 V/μs.
  • Wide gain bandwidth: 16 MHz (G = 1).
  • Unity-gain stable.
  • Rail-to-rail output.
  • Wide supply range:.
  • ±2.25 V to ±18 V, or 4.5 V to 36 V.
  • Dual-c.
